OIL BURNER.

Application filed April 26, 1926; Serial No. 104,784.

My invention relates to oil burners of a type particularly adapted foruse in furnaces for heating houses with either steam, hot air or water.

In the accompanying drawing:

Fig. 1 is a perspective partly sectional view of a furnace equipped with my improved oil burner.

Fig. 2 is a diametrical section of one of the gas generators of the burner.

Fig. 3 is a plan view of one of the draft regulating devices.

Referring to the drawing by reference numerals, 5 designates a heating furnace having a grate 6 upon which in ordinary furnaces fuel such as wood, coal or cokeis burned. The greater part of the fuel door 7 and the ash pit door 7" are broken away to expose more fully the new burner, which is shown as standing upon the grate bars 6 and consisting of a cylindrical main member 8 fully open at the bottom end and having its top opening contracted some. 9 is an inverted bell-shaped member or pan secured within the member 8 by bolts or screws 10 and spacing blocks 11 leaving a circular air passage 12 between the two members. Resting upon the member 8 isa truncated funnel 13 having its inner edge 14 projected downwardly and guided by the top edge 15 of the member 8.

Mounted on pipes are several gas generators 17 each of which is heated by a gas burner 18 receiving gas at 18 through a pipe 18 from the generator 17 when the oil therein is sufficiently heated. The main portion of the flames from the burners 18 serves however to heat the air that passes, as arrows 19, up into the heating apparatus 5.

Each pipe 16 is extended downwardly through the part 13 and 15, as at 20 in Fig. 1 and is threaded in the top end of the duct 21 formed in or upon the side of the pan 9 and having in its lower end secured a pipe 22 which extends horizontally as 23 to regulating valves 2 1 which control the flow of fuel from a main oil intake pipe 25 receiv ing fuel through its end 26 from an oil tank (not shown).

The flow of oil through the pipe 25 may be controlled by a thermostat (not shown) connected with a valve actuating arm 29. The pipe 25 also has asafety valve 27 which is closed automatically by an internal spring as soon as a lever 30 is swung downwardly 16 above the funnel 13 i by the weight of a small bucket 28' suspended from said lever and arranged to receive from-a drippipeBl any oil that may drip or overflow from the burners 18. If such overflow should take place the oil will be guided by the funnel shaped flange 13 down into pan 9 where it will escape through a hole 32 in one side of a vertical pipe 33, from which it runs into pipe 31 which is a portion of the plpe 31.

34: is a circular bafile plate threaded upon the upper portion of the pipe 33 and the raising and lowering of which is done by rotating it, and, its object is to regulate the amount of air draft upwardly through the opening 12.

The valves 2a are accessible through the ash pit door 8, which in some cases may have the door itself removed.

In cases where the ordinary grates '6 may allow too much air to pass upwardly outside the body piece 8 I provide several segmental pieces as 35 in Fig. 3 of either asbestos or sheet metal and place the required number of them upon the grate about the element 8.

Upon the bottom of each gas generator or chamber 17 is a heavy lining 17 (Fig. 2) of aluminum, the object of which is to more readily conduct the heat from the burner 18 to the oil admitted into the chamber.

If the heating furnace has its grates in an extra low position a few bricks may be placed between the grate bars and the part 8 of the burner. Or, if the grates are unduly high up they may be removed and replaced on bricks as low down as desired.

In the operation, one,'two or even all three of the valves 24 may be opened according to the number of the burners 18 needed to produce sufficientheat according to requirements; The thermostat (not shown) may be attached in such manner as to control the number of valves in actual use.

All the pipes 31 and 32 are gathered so close together that they may easily be passed. through the grate 6 in a single place, or by removing one grate'ba-r.

I claim:

1. An oil burner comprising a cylindrical hollow base contracted at its top and arranged to receive air into its bottom opening, a truncated funnel resting on said top, a funnel-shaped pan mounted centrally in and spaced from the sides of the cylindrical base, a series of oil delivering pipes extendwhich the ventral stud is, tubular and has a. lateral hole near above the bottom 01' the pan, and a hep pipe secured 1n the base at 1 I) the pan directly belew the stud and GKtGlIdQd. hm-izentntty therefrom.

:3. The etructm'e slmeil'ied in claim 1, in which :1 portion e'teuch oil delivering pipe ('HHSiSt'i; 0t a duct extending radially in the 2 wide of the pain.

in te.-:timeny whel'm't I efi'ix my signatm'e.
